| 摘 要： | 采用原子转移自由基聚合法(ATRP)在纳米S iO2表面接枝PBA,并采用TEM及力学性能测试等手段研究了纳米S iO2及S iO2-g-PBA复合粒子的添加对聚氯乙烯(PVC)力学性能的影响.结果表明:用ATRP聚合方法有少量的PBA接枝于纳米S iO2表面;所制备的纳米复合粒子在PVC中较纳米S iO2粒子分散均匀,使纳米PVC/S iO2-g-PBA纳米复合材料的拉伸强度、断裂伸长率及断裂能均明显高于PVC及PVC/S iO2复合材料.

| Abstract: | In the paper,poly(butyl acrylate)(PBA) was grafted onto the suface of nano-silicon dioxide(SiO2) particles through atom transfer radical polymerization(ATRP) of butyl acrylate.Moreover,the effects of nano-SiO2 particles and nano SiO2-g-PBA composited particles on the mechanical properties of Poly(vinyl Chloride)(PVC) were studied by means of transmission electron microscope(TEM) and mechanical properties testing.The results showed that PBA was grafted on to the surface of nano-SiO2 through ATRP reaction.Mor... |
